Being overweight in midlife is associated with lower cognitive ability and steeper cognitive decline in late life

Background: Although an increasing body of evidence links being overweight in midlife with an increased risk for dementia in late life, no studies have examined the association between being overweight in midlife and cognitive ability in late life. Our aim was to examine the association between being overweight in midlife as measured by body mass […]

Treating neuropsychiatric symptoms in dementia with Lewy bodies: a randomized controlled-trial

Sensitivity to psychotropic medications presents a therapeutic challenge when treating neuropsychiatric symptoms in patients with dementia with Lewy bodies (DLB). We compared under randomized, double-blinded conditions the tolerability and efficacy of citalopram and risperidone in the treatment of behavioral and psychotic symptoms in patients with DLB and Alzheimer disease (AD). Thirty-one participants with DLB and […]

Efficacy of cognitive training programs based on new software technologies in patients with Alzheimer-type dementia

The study aims to assess the efficacy of the Big Brain Academy (BBA), a computerized cognitive training program (CT) based on video games, compared to the Integrated Psychostimulation Program (IPP), a classical CT tool for patients with Alzheimer’s disease (AD). A total of 45 patients with AD at the mild stage were randomly assigned to […]

Differences in regional brain metabolism associated with specific formulations of hormone therapy in postmenopausal women at risk for AD

Differential cerebral metabolic effects of various hormone therapy formulations, and their associations with cognitive status, remain to be established. The principal aim of the current study was to assess relationships between regional cerebral metabolism and estrogen-based hormone therapies. Postmenopausal women (n=53) at elevated risk for Alzheimer’s disease (AD) were on estrogen-containing hormone therapy for at […]

Improved visual hallucination by donepezil and occipital glucose metabolism in dementia with Lewy bodies: the Osaki-Tajiri project

Deficits in the cholinergic system are pronounced in dementia with Lewy bodies (DLB) and are more severe in patients with visual hallucinations (VHs). The aim is to identify the occipital glucose metabolism patterns by positron emission tomography (PET) and the changes following donepezil treatment. 13 DLB patients with VHs were enrolled in the study. After […]

Effect of Rikkunshi-to on appetite loss found in elderly dementia patients: a preliminary study

Background: Functional gastrointestinal symptoms are frequently found in elderly dementia patients. In such a case, we attempt treatment by the administration of antidepressants or second-generation antipsychotics. However, these medications have a risk of side-effects. In the present study, we carried out oral administration of Rikkunshi-to to elderly dementia patients with appetite loss, and examined its […]

Sustained effects of once-daily memantine treatment on cognition and functional communication skills in patients with moderate to severe Alzheimer’s disease: results of a 16-week open-label trial

The present study evaluated the effects of once-daily memantine (20 mg) treatment on cognition and communication in patients with moderate to severe Alzheimer’s disease (AD). In a multicenter, single-arm open-label study, outpatients diagnosed with AD (MMSE < 20; n = 97) were titrated from 5 mg to 20 mg once-daily memantine over 4 weeks. Once-daily […]

Dementia caregivers’ responses to 2 Internet-based intervention programs

Purpose: The aim of this study was to examine the impact on dementia caregivers’ experienced stress and health status of 2 Internet-based intervention programs.; Design and Methods: Ninety-one dementia caregivers were given the choice of being involved in either an Internet-based chat support group or an Internet-based video conferencing support group. Pre-post outcome measures focused […]

Quality of life and the effect of memantine in dementia with lewy bodies and Parkinson’s disease dementia

Aim: To investigate quality of life (QOL) and the effect of memantine treatment in patients with Lewy body dementias.; Methods: A secondary analysis of a randomized controlled study in 70 patients with Parkinson’s disease dementia (PDD) or dementia with Lewy bodies (DLB) over 24 weeks using caregiver-rated QOL-Alzheimer’s disease (AD) in domains according to the […]

A randomized placebo controlled trial of homocysteine lowering to reduce cognitive decline in older demented people

Introduction: Whether homocysteine lowering by B vitamins can reduce cognitive decline in Alzheimer disease and vascular dementia patients is unclear.; Methods and Materials: 140 subjects with mild to moderate Alzheimer disease or vascular dementia were randomly assigned to take 1 mg of methylcobalamin and 5 mg of folic acid, or placebo once daily for 24 […]
